等温淬火是我们所熟知的一种淬火工艺,在生产中也早有应用,但就目前情况来看,主要还是用于减少变形和防止裂纹。随着人们对等温相变组织形态、应力状态等与性能关系的深入研究,以及近年来大量工艺实践表明,充分发挥等温淬火的作用,能改善工具钢的强韧性,有利于提高钢的耐磨性和瘫劳强度,因而是提高工模具使用寿命的又一有效而简便的工艺途径。为了发挥等温淬火提高工模具使用寿命
Isothermal quenching is a well-known quenching process that has long been used in production, but for the moment it is mainly used to reduce distortion and prevent cracks. With the in-depth study of the relationship between isothermal transformation microstructure and stress state and properties, as well as a large number of process practice in recent years show that giving full play to the role of isothermal quenching can improve the toughness of tool steel is conducive to improving the wear resistance of steel Sexual and paralysis strength, it is to improve the service life of tooling Another effective and easy way of the process. In order to enhance isothermal quenching tool life
